Well, looking at the code, this should not happen. The question is: how
do you ensure, in the code that calls rt_task_join, that the thread
being created had the time to call rt_task_shadow? In other words, are
you sure that you are not passing rt_task_join an uninitialized RT_TASK?

So, as usual, we are missing a simple standalone test showing the issue
you have.
